CALIFORNIA, A CORPORATION OF "CALI- y BINDER.

Application mea october 2s, 1925. serial No. 65,404,

lhis invention relates tobinders and particularly to binders for l looseVleaves of books, such, lor example, Aas check books and receipt books.i y

An object" of the invention is the provision of a sectional binder, thesections of which may be readilyand permanently intcrlocked. i i Y lAnother object of my present invention I is the provision of a bindervcapable of binding leaves together insuch a manner that there is nopossibility of any of the leaves being accidently lost. 4 p 1 A furtherobject of my invention isthe l provision of a sectional binder, one ofthe sections of which may be secured toa book cover-,by themanufacturer,` while the other section may be readily applied by theperson who inserts a filler in the book cover.

A'still further object of my invention is the provision of abindercapable ot' withstanding comparatively high pressure without beingdamaged.

Another object of myy invention is the provision of a binder free fromoutwardly extending projections so that the leaves held by the binderwill not be damaged byv being turned. v

Another object of this invention is `the provision of a binder which maybe secured to a book cover in a manner permitting the top o'lf the coverto be folded under the back oi'i the cover, whereb the space occupied bythe open book may be economized.

gether with such other objects as may subsequently appear, thisinvention resides in the construction and arrangement of parts`hereinafter described and claimed, and illustrated in the accompanyingdrawings, in which i Figure l. is a perspective View ot an open hookcover with a liller ot loose leaves therein, bound together by twobinders of my inrcntion.

Figure 2 is a lragmentary vertical section ot the binder, filler andcover shown in Figure 1, the book in this view being closed. Figure 3 isa vertical section taken on the line 3-3 of Figure 2 in the direction ofthe arrows, shown in Figure 2, and

Figure '4 is a perspective view of the binder ofiny invention. v

Referring to the drawings `for more de-` `9 around to the points lVit-hthe foregoing objects in view, to`-v opposing lowerscction 6, both ofwhich i.

sections are preferably formed from coinparatively broad metallic bandsorribbons. The upper section 5 inverted U comprising an arcuate upperend portion 7 8. The side portions of the metal strip or ribbon fromwhich the section 5 is formed` are bent inwardly and, from the points yp 10, are pressed back into contact with the vertical side portions` 8and the upper arcuate portion 7. Below the points 9` and 10,` however,the inwardly bent side portions of the band from which the member 5 isvformed, Vare spaced from the vertical portions 8, thus forming guide imembers `9? and pockets 10a-between the guide members 9 and the verticalportions 8. The vertical portions 8 of the section 7 are punched to formprojections 11 which slope inwardly and upwardly, and these projectionshave horizontal upper edges 12 broken away from the vertical portions 8of the section 5.

The lower section 6 of the binder is U- shaped and comprises a bottom 13`and vertical sections 14 at right angles tothe bottom 13. The verticalsections 14 are preterably resilient and are punched to provide`apertures 15. The bottom 13 of the lower section Gfis provided with anaperture 17 through which extends a rivet 18 provided for the purpose ofbinding the lower section to the back cover 19 of the book shown inFigure 1. Two of the sections G are riv- 'eted to the back cover of thebook shown in Figure 1 and yare spaced from each other.

A filler 21Y which consists of checks 22 to ther-ight of the scoring 23,and ot' stubs 24 to the left of the scoring 23, may be placed on thelower sections 6 before the upper sections 5 are made to engage thesections 6. The upper and lower stub portions 24 are is given the formof anA and vertical side portions ifi() provided withv apertures 25through which y one of the vertical portions 14 of each section 6extends. The upper sections 5 may then each have one of their verticalrportions 8 inserted into the apertures 25. The sections presseddownwardly, the verticals la, due to their' resiliency, are snapped overthe projections 1l, which projections then extend through the apertures15. The upper edges of the apertures 15, which are preferably straight,Vlie above the edges 12, which edges prevent the sections 6 from beingwithdrawn from the sections 5. the turned-in side portions of the ribbonfrom which the section is formed, yare pressed against the verticalportions 8 above the points 9, or, in other words, the `pocket 9lllterminate at the points 9, so that the movements of the sections 5 and 6toward each other are thus limited.

It will thus be readily appreciated that when the sections 5 and 6 of myimproved binder are snapped together, they are permanently inter-locked.

From the foregoing description, it will be seen that I have provided adevice which is capable of fulfilling the objects of my invention ashereinbefore stated.

Although I have shown and described one embodiment of my invention, itto be understood that the same is susceptible of various changes; and Ireserve the right to employ such as may come within the scope of theappended claims. l

I claim: Y

1. A ring for loose-leaf binders comprising As previously stated,

upper and lower substantially U-shaped mating members, forming apermanently closed loop or ring, one of said members having guidewaysfor the reception of the uprights of the other member, the uprights ofone of said members having apertures and the uprights of the othermembers having projections adapted to be sprung into said apertures whensaid members are Vbrought together'into interlocking position.

2. A device of the type described comprising a loose leaf binderconsisting of two members adapted to telescope one Within the other forforming a ring and cooperating catches carried by said member forpermanently securing them together.

3. In a binder, afU-shaped member having` its curved edges bent backupon themselves for reinforcing the member, the baeluvardly bent portionbeing spaced away from the walls of said member for a predetermineddistance for providing guideways, a second U-shaped member having itsends receivable in said guideways, and means carried by both of saidmembers for permanently securv ing said members together, said firstnamed member permitting leaves' carried thereby to be swung over in thesa'memanner as the movement of the leaves in a book.
